Since my weather station (Davis Vantage Pro) moved to British Summer
Time, BST on the 27th March '05 when the station uploads records to
the Weather Underground website I get duplicate records on their
website. I had been uploading for nearly five months (I started
after BST ended!) without any problems and nothing ever changed at my
end (but for the time!)

I've tried resetting the date and time to synchronize the time on the
station with the software and PC; disabling the 'Auto-Detect' feature
and manually enabling daylight saving but have never been able to
solve the problem.

My station ID is 'IEDINBUR1' and I don't think I'm alone with the
problem. The only way I can get around this is to upload once a day
to minimise the spureous records.

The information I get in my event log is, e.g. "Duplicate entry
'IEDINBUR1-2005-04-02 13:49:45' for key 1".

Does anyone have any suggestions how to resolve - Davis and Weather
Underground didn't offer any solutions.

Look forward to your suggestions.

I get the 'Duplicate entry........for key 1' as well in the Weatherlink log
but it doesn't cause any problems with the Weather Underground display. Now
I've had a look at your data for yesterday and in most cases the parameters
do change from line to line. I assume you mean to have 5 minute intervals.
Weather Underground is a strange beast which usually runs smoothly. However
if you make any manual alterations in Weatherlink it either takes time to
update or ignores your changes completely.
Just done a Google on this problem and find that the duplicate key message
is a known bug on Weatherlink 5.5

All the best
